TL;DR: In the batch experiments of cadmium(II) adsorption, the removal capacity of biochars improved under higher temperature, especially at 800°C and 900°C even one order of magnitude higher than that of the commercial activated carbon.

TL;DR: In this paper, static equilibrium experiments were conducted to distinguish the adsorption performance between the two valence states of chromium on biochar derived from municipal sludge, showing that Cr(III) is much easier to be stabilized than Cr(VI).

TL;DR: In this paper, the authors investigated the impact factors and the mechanism of cadmium adsorption on biochar derived from municipal sewage sludge and found that an appropriate dosage of biochar is sufficient; in the experiment, 2% is the optimal dosage for the largest removal capacity.

TL;DR: The improved photocatalytic activity may be attributed to the accelerated interfacial electron-transfer process and the significantly prolonged lifetime of electron-hole pairs imparted by graphene sheets in the nanocomposites, but excessive graphene and the inhomogeneous aggregation of TiO2 nanoparticles may decrease photodegradation efficiency.

TL;DR: EEM-PARAFAC/FRI enabled a rapid and accurate assessment of biological stability of landfilled MSW and C1/C3 F(max) ratio was found to be the most sensitive indicator of the biostablization state of the landfilledMSN.
